Precautions

This equipment has been designed and manufactured to meet international safety standards but,

like any electrical equipment, care must be taken if you are to obtain the best results and safety is

to be assured.

…………………………….

DO read the operating instructions before you attempt to use the equipment.

DO ensure that all electrical connections (including the mains plug, extension leads and inter-

connections between the pieces of equipment) are properly made and in accordance with the

manufacturer’s instructions. Switch off and withdraw the mains plug before making or

changing connections.

DO consult your dealer if you are ever in doubt about the installation, operation or safety of your

equipment.

DO be careful with glass panels or doors on equipment

…………………………….

DON’T remove any fixed cover as this may expose dangerous voltages.

DON’T obstruct the ventilation openings of the equipment with items such as newspapers,

tablecloths, curtains, etc. Overheating will cause damage and shorten the life of the equipment.

- 3 -

DON’T allow electrical equipment to be exposed to dripping or splashing, or objects filled with

liquids, such as vases, to be placed on the equipment and don’t handle the power cord with

wet hands.

DON’T place hot objects or naked flame sources such as lighted candles or nightlights on, or close

to the instructions.

DON’T listen to headphones at high volume, as such use can permanently damage your hearing.

DON’T leave equipment switched on when it is unattended unless it is specifically stated

that it is designed for unattended operation or has a stand-by mode. Switch off using the

switch on the equipment and make sure that your family knows how to do this. Special

arrangements may need to be made for infirm or handicapped people.
